消息处理
<h2>命令消息处理</h2>
<h3>单命令消息处理</h3>
<p>一个控件Id绑定一个消息处理函数，如下所示：</p>
<ul>
<li>头文件</li>
</ul>
<pre><code class="language-c">void OnBtnClickedCommand(UINT uNotifyCode, int nID, CView* pView);
SKINUI_DECLARE_MESSAGE_MAP()</code></pre>
<ul>
<li>源文件</li>
</ul>
<pre><code class="language-c">SKINUI_BEGIN_MESSAGE_MAP(CMainDialog, CDialog)
ON_SKINUI_COMMAND(IDC_BUTTON, OnBtnClickedCommand)
SKINUI_END_MESSAGE_MAP()
void CMainDialog::OnBtnClickedCommand(UINT uNotifyCode, int nID, CView* pView)
{
}</code></pre>
<h3>范围命令消息处理</h3>
<p>一个控件Id范围绑定一个消息处理函数，如下所示：</p>
<ul>
<li>头文件</li>
</ul>
<pre><code class="language-c">void OnBtnClickedCommand(UINT uNotifyCode, int nID, CView* pView);
SKINUI_DECLARE_MESSAGE_MAP()</code></pre>
<ul>
<li>源文件</li>
</ul>
<pre><code class="language-c">SKINUI_BEGIN_MESSAGE_MAP(CMainDialog, CDialog)
ON_SKINUI_COMMAND_RANGE(IDC_BUTTON1, IDC_BUTTON2, OnBtnClickedCommand)
SKINUI_END_MESSAGE_MAP()
void CMainDialog::OnBtnClickedCommand(UINT uNotifyCode, int nID, CView* pView)
{
}</code></pre>
<h3>更新UI命令消息处理</h3>
<p>SkinUI会在需要的时候发送更新UI命令消息用来更新UI组件的状态。主要存在以下几种情况：</p>
<ul>
<li>按钮的禁用；</li>
<li>菜单的禁用；</li>
<li>菜单的选中；</li>
</ul>
<h4>按钮的禁用：</h4>
<ul>
<li>头文件</li>
